Shapeshifting Hunter for favored enemy?

[Buba HoTep]

"Benefit: Your levels of druid stack with your ranger levels for determining when you select your next favored enemy. Also, your ranger levels stack with your druid levels in determining the number of times per day you can use your wild shape class feature, up to a maximum of eight times per day."

So, does this mean that if I have a 1st level Ranger / 19th level druid he'd have all the favored enemy bonuses of a 20th level Ranger?
I'm unclear on the exact benefits of "...for determining when you select your next favored enemy".

That's exactly what it means.
